TO ALL lVHOM IT MAY CONCERN: n

Be it known thu-t AI',}GrI-:0RGE H. BAILEY., of JerseyCity, Hudson county, State of New Jersey, have invented n new and improved Machine for Making Waiter, Gos, und Sewerage lipes; and l do hereby declare that the following is e full, clear, :ind exact description thereof, reference being hud to the accompanying drawings, nniking :t part of this specification, in which Figure l is o. sectionA taken in c vertical plane through the centre of the machine showing the plunger elevated, l v

, Figure 2 is n similar view of the same ports showing the plunger depressed.v

Figures 3 und 4 are sectional views taken in horizontal pinces through the machine.

Figures 5 und 3 repre-:ent u plunger with spiral cutters formed on its lcunicoli end.

Similar letters of reference indicateCorresponding parts in the several iigures.

This invention relates to an improvement on the manufacture of pipes, which are formed either of a. combinnticn of iron and cement, or of ceinent only; end it Vconsists in subjecting the materiel composing the pipe:v to powerful 'pressure whilst in n. plastic stare, therebyv greatly increasing the strength and solidity of the seme, und facilitating the manufacture.

To enable others skilled in 'the crt to understand my invention, I will describe its construction and operation. i

In the accompanying drawings, A represents the pipe to be lined, or the mould to be lled, as the case muy be. t is set in en upright position on the: bed-plate B, und kept iryplsce by ineens of rings or collars C C. I) ic a sm-ooth, poiished plunger, oi' the exact size of inner here of the pipe when finished, and somewhat ongcr thun such pipe. if; is inode to travel in a. vertical direction by means o" the cross-head E, on'the guide`- rods F F. which latter orcsupported by the 'framework G. 'The plunger D works through the upper ring or coller G, which is bored out so :is to allow this plunger to move freely, und .vhich is recessed on the under side to receive the upper end of the pipe A, as shown in fig. 2. This collar C is kept in position by the guide-rods i? F, und works {reeiy up and deren on rhein. The lower end of the plunge'v terminates in' a. cone, which may have spi-rel lcutters, a a, formed on it, as shown in figs. 5 and 6. The bed-plute B is recessed to r'eceive the conical und of thc plunger, und'is perforated with an opening, b, which may be provided with n. vulve -or plug so that it. con he opened or closed :it pleasure. rh'en set in proper position the centres of the cross-head E, collar C, und bed-pluto B, are :ill in the sume vertical line, The upper collar C has a series 0i' scroll openings or notches,A e ve,'cvteinling from the appel end of the pipe A to the top side of the coller. The plunger ua havevepplied to its upper end e. screw, or lever, or any convenient arrangement of power for forcing it down. screw, G', is represented in the drawings working through s. nut in the crose-heud. When power 'is applied to depress the plunger. bolts dd are inserted through the standards of frame G above the crossheud, andthe collar C, at 4the fop of the pipe A, is secured in like manner. Two rods gg ore attached to the under side of the cross-headE, and poss through the supporting-bor of the coller C, with adjusting nuts on'their lonfer ends, as shown at h, in iigs. 1 and These rods are of' such length ns, w'hen the pipe is r:ornpletely lined and the plunger elevated to o sufficient height., to mise the top collar U fron'r'the top of the pipe.

4 The operation ci' forming :i pipe is os follows: dThe iron pipe A. to be lined, or the mould to, belled, as the euse muy be, is ser. ou the helpline, the plunger being raised entirely free freinv the pipe 'oy means'o a cran or windluss. The holen: the bottom is closed bye. plug or vulve, und :rsuiiicient quantity of .cement thi-ouin in to forni the pipe, The pl'unger'is'loirered suiicently to allow the upper end of the'pipe to enter the ice-ess in the lower 'side of the coller C, and when. thus adjusted the plunger is allowed to Full rapidly, displacingitc sement in front of' it. Asthe means of escape at the bottom is closed the cement is forced to rise, 'filling Athe space between thc plunger and the pipe oi' mould. The plunger by its own weight and the momentumfcqtiird will enter sonic dstunee into' the soft cement. As soon es the plunger luis ceased to fall, the belts dan inserted uoove the cross-head, and thepcv'ver applied, forcing the plunger to poss entirely to the bottom of' 'he pipe until itis-trikes the bed-piatte. If, et the same time, the plunger .is turned about its axis, the sdvontdge is gained ci' rubbing down the surface of the cement, greatly :riding in compneting and smoothing it` ,'l.

advance of the plunger will he facilitated lav the applioition o? spiral critters to thelower gend. As their.

tills with cement tue air is driven out through the rents e c, through the collar C, und the filling of' the'pipc is indien-tell by the (wf:

-t to the plunger, it is occnsionnlly turneil untilI the cement is vrntbelow. lo prevent the cement setting i`: suiiiciently set te u'utintnin its shape, when itis '.vitlrlruin, the vent nttne bottom being rst opened to pevent n vacuum being formed under the plunger. I

l'n the nbove description I have set forth the pio-Wer used for forcing the plunger downvs n. screw. I do not, however, continu myself to the screw7 n; earn or other convenient poner may be applied without effecting the principle of my invention. 'llic forni given te the enil of the Yplunger assists it in displacing the cement,

and 'at the seme time gives n, certain menus of exactly centrino* the plunger when it reaches the bottom.

The operation and effect will be substantially the sume by reversing the arrangement of parts.; thntis' to say, the plunger muy remain stationary, or hure only n. rotnry motion, unil the pipe charged with ceuient forced flown b v power applied to the upper -enil yof it. Whilst the principle herein set forth is applicable to the p-nrt of pinstie mnterinl, ofiwhntever form, it is peculiarly :ulupted to v formation of pipes composed in whole` 'the manufacture of pipeseomposed elf iron :11ml cement 'murio in the nell-known form of Knights patent,

which the iron is forme With a. tape firing when lineil n grentcr thickness of cement at enc end than at the- I .7, D other. By the method herein describ'oiL-fthe pipes being lined with the largest ends down, and -the cement being forcei upward from the bottom to the top, it :is Aconstantly pressed into a. conti-netted space, und must necessarily be greatly eompresseil. The cement 'cnn escape ut the top only when all the space below hns been filled. The

object aimed at und nt'tain-ed by my invention is to furnish a. more solid anfl perfect pipe than can be mede by any of the methods new fi-n use. By the method of lining with the`eore drawn througlfthe pipe,' which is the one in commen use, the cement is simply leid :ign-inst the iron pipe cr mould by the rapid passage of theA` core without beingsubjeeted to any considerable pressure, und consequently the'lining is liable tolflrop oli' and settle toward rthe bott-om =of 'e -pjpe while in n green state, leaving spaces to be patched by hand.

11n-ving -ileseribe'cl my invention, what I claim ns new, and desire to secure by Letters Patent, is-` L The employment, inthe manufacture oi' pipes composed in whole or in pnrt of cement orpla-stic material., of e. plunger, either movable or stationary, which is shaped substontinllyos set forth, either with or Without spiral -'cutter-si, and which by the application ot' power or by its own 'weight and momentum displuces thc cement in fron-t of it, causing the lutter to adhere to the pipeand rendering it solid und compact, substantially as i described.

'2. The combination, '.vitliithe plunger D, of the top and bottom collars CC', with vent holes for the admission'nnflesenpe of air, s'ubstnntiniiy as described. i

3. The applica-tion of lifting-foils gg to the collar C, for lifting this collar when thelplunger is raised, substantiallyas described. f

LL. I claim n. plunger working within. a. metallic pipe or mould, having one or both ends closed so ns to more 'perfectly and forcibly compnet the cement or plnstic materiel within in-substantially as described.
